IMPROVEMENT IN MECHANICAL MOVEMENTS.

S .-eoitication forming part of Letters Patent N 0. 190,066, dated April 24, 1877; application filed June 16, 18761 To all whom it may concern Be ii'i'kliOWl that I, NILS NILSON, of Min neapolis, in the county of Hennepin and State of Minnesota, have invented certain new and merits; and I do hereby declare that the folthereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention consists in the construction and arrangement of parts of a mechanical movement for producing a reciprocating motion and regulating the same, sul'istantially as hereinafter more fully explained and pointed out in the claim.

In the drawings hereto annexed I have repengine, in which-- Figure l is a front elevation, and Fig. 2 is a top plan.

Similar letters of reference indicate corresponding parts in both the figures.

A is the frame of the engine, having my improvement. B is the steam, water, or air cylinder, having a piston rod, b,- and (Jv is a force or feed pump, having piston-rod c. The piston-roil b of cylinder B operates a short lever, D, hinged at d-in the upper part of frame A by means-of the intervening oscillating link b, and the rod 0 of pump 0 is hinged in a similar manner (by the oscillatin frame A.

consists of two parts, I) and 1), between which is arranged the single lever E. Both I) and I) are slotted, so as to form guides k for slides fthat are pivoted upon the end of a bentrod, F. Slidesf may be placed in any desired position within the slots 70 by operating thescrew G, having its bearing g upon the end of the long lever E above the pivoting point e, and engaging with the bent rod F, as shown in the top plan, Fig. 2, in such a manner that by operating the screw G the bent rod F and the slides f may be made to move forward or backward within the slotted lever l) l). The slides ff are united by a short rod or cross-piece, h, and the long lever it is slotted at t, the rod h sliding within the slot 0'. H

By this arrangementit will be observed that when the slides f. operated by the screw G and bent rod F, are moved forward in the direction of the arrow, the short rod It will move with them, thereby changing its bearing-point upon the lever E within its slot 1', and consequently lengthening the stroke of the pistonrod 0. When the screw G is turned in the opposite direction the slides fand rod F are made to recede within the guide-slots It within the lever .l) 1), and with them rod /b is moved back in its guide-slot in the lever E, thereby decreasing the upward pitch of said lever, and the piston-rod c of the pump (J being hinged upon this lever its stroke is consequeutly decreased in the same proportion.

From the foregoing description the operation of my improvement will be readily understood without any further explanation. The construction and arrangement of parts is such that it requires very little power to adjust the stroke of pump 0, which may be adjusted to any given position by simply operating the screw G, which may be done while the machine is in motion without it being stopped.

Having thus described my invention, l claim and desire to secure by Letters Patent of the United States- A mechanical movement for producing a reciprocating motion and regulating the same, consisting of the slotted levers l) D E, beat rod ii, and adjusting-screw G, all arranged and combined to operate substantially in the manner and for the purpose herein shown and. specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
